Wagon-jack.



'W'AGN-JACK.

Specification of Letters Patent.

patented d s,

To all 'whom t may concern.-

Be it known that l, LAWRENCE LARsoN, a citizen ot the United States ofAmerica, residing at Milford, in the county orn Dickinson and State ofIowa, have invented new and useful Improvements in llVagon-Jacks, ot'which the following is a specification.

rl`he present invention relates to improvements in wagon jacks, and isdesigned particularly for u-se during the operation or dumping a wagonwhich is provided with removable bottom boards.

The primary object ot the invention is the provision of a device whichmay be manipulated with facility during the operation of dumping a wagonload of sand, gravel, or soil, in which the bottom of the wagon is madeup ot transversely arranged, removable boards which are independentlysupported and which'may be independently detached from the wagon bottom.l/Vhile the wagon jack is capable of use in other ways and for other.purposes, it is especially adapted tdbe supported above the sides of awagon and arranged transversely of the wagon, and the deyice is movablysupported, so that it may be'adjusted as desired.

The invention consists in certain novel combinations and arrangements ofparts as hereinafter set forth and claimed.

ln the accompanying drawingshave illustrated one complete example ofthev physical embodiment of my invention, constructed according to thebest mode l have so tar devised for the practical application of theprinciples of the invention.

Figure l shows a wagon body, in longitudinal section, w'th the wagonjack supported thereon. and illustrated in position to remove one of thebottom boards. Fig. 2 is a plan view ci a portion or" Fig. Fig. 3 is atransverse section ot the wagon ack. fts a perspective view of the jack.Fig. 5 is a perspective view of the hook portion or the wagon jack.

ln the practical vapplication of my wagon jack, it is used preferably inconnection with a dumping wagon which is provided witi transverselyarranged bottom boards, and to illustrate my invention I have employed awagon body havingthe two side members l and 2, the rear tail gate 3, andthe front dash board et, and suitable devices are illustrated forsupporting the tail gate and front dash board. Beneath the sides 'are apair or' longitudinal bottom bars 5 'and 6, three cross bars 7, 7, 7,are illustrated beneath the wagon body, and two cross bars 8, 8 -areillustrated above the wagon body as supporting members. Suspendedbetween the two longitudinal bottom bars are the removable transverselyarranged bottom boards 9, having their ends supported upon the bottombars 5 and 6, as illustrated in Figs. l and 2. It will be readilyunderstood that these bottom' boards are to be removed consecutively inthe process of dumping the wagon land emptying the contents through theopening in the bottom of the wagon. To accomplish this purpose l"provide the wagon jack illustrated herein, which when not'in use, may besupported upon the wacron side l by means of a pair of hooks as 10-l0. I

The wagon jack is preferably made up of a pair ofparallel spaced barsll-ll joined at one end by a blocl: lf2, and at the other end by a strap13. rlfhese four members are rigidly secured together with a spacebetjreen through which the chain 14textends, and -in which thesupporting brackets l5-l5 are located. rlhese brackets are metal plates,each secured by a pair of bolts 16 to the respective'bars orn the wagonjack, and the brackets project above the top surface of the bars asillustrated. The brackets are perforated as at L7', and in the gures ofdrawing a pivot bolt 18 is passed through the upper pair of perforations'17, 'and the lever 19 is pivoted on the bolt and adapted to swing inthe vertical plane between the two parallel barsn To the short arm 20 ofthe lever, the chain 14 is attached at 2l. The chain extends downbetween the two bars lil-1l, and may be made up of suitable links, butthe lower end of the chain has a pair of special links 22 to which thehook 23 is pivoted and these links 22 may be used 'to adjust the lengthof the lifting chain of the lever. y The purpose of the wagon jack iscally illustrated in Figs. will be seen that the l graphiand 2, where itjack is arranged transversely of the wagon body with the strap 13resting against the inner edge of the side ,2 of the wagon body, thebars ll-ll of the jack are resting upon the upper edge or the wagonbody. ln this manner the strap 13 holds the jack in proper position, andthe jack may be slid along' on top ot' the wagon body sides as it U0 fis used. The chain llldepending through the wagon jack is in positionfor the hook 23 and the under Jfaces of of the to be engaged under theouter edge of a bottom board, as shown in Fig. '1, and it will bereadily understood that when pressure is applied to the lever 19, andthe long arm is pressed down, the chain will lift one edge of the bottomboard, thus tilting it to'dislodge the material resting thereon. Theboards may be tilted and permitted to drop through the opening in thebottom of the wagon, or they may be disposed of in other suitablemanner. As the process of unload ing the wagon progresses, the jack isslid along to the left in Figs. 1 and 2, and each succeeding bottomboard is tilted and re,- moved, and the contents of the wagon isdisplaced and permitted to fall through the open bottomA of the wagon.

As before stated, when the jack is not being used, it is hung at theside of the wagon by means ofthe two hooks 10-10 so that it will be outof the way when not in use, and yet accessible when needed. The altitudeof the pivot for the lever 19 may be changed by utilizing theperforations in the supporting bracket plates 15. 'Io adjust the heightlever the bolt 18 is removed, and the lever lowered and then thebolt isinserted Copies of this patent may be obtained for ve cents each, byaddressing the through the alined openings in the bracket plates and thelever and then thesnut 24and then tightened on the bolt 18. I

From the above description taken in connection with my drawings it willbe apparent that I have provided a comparatively perfect device forperforming the functions set forth as the purpose and object of myinvention, and the wagon jack has proven by actual test, to be anefficient, durable, simple, and comparatively inexpensive device forthis purpose.

What I claim is:

The combination with a wagon body having individually removabletransversely arranged bottonrboards, of a movable jack adapted to restupon the top 'of the wagon body and comprising a pair of spaced bars, afiller block and a guide vstrap,apair of brackets supported between thespaced bars, a pivoted lever adjustable in said brackets, and a chainand hook attached tothe lever adapted to lift the bottoni boardssuccessively.

In testimony whereof I aiiix my signature.
